Abstract: A hybrid type permanent magnet bearing system which utilizes four permanent magnet rings to replace the mechanical bearings. These rings are divided into two separated groups along an axis, where each group has an inner ring and a separated outer ring. At least one permanent magnet ring has a surface facing the gap between the two groups but being not vertical to the axis. Hence, inside the gap, the magnetic field between these permanent magnet rings is not non-uniform over different directions, and then it may behave as the axial and radical bearing simultaneously.

Abstract: An axial passive magnet bearing system utilizes the friction-less characteristic of non-contact type permanent magnet bearing to minimize the disadvantages induced by frictions. For example, both the energy and material loses of the mechanical bearing. Two permanents magnet are made of permanent magnet materials and positioned over two opposite surfaces of two mechanical structures, where mechanical bearing(s) is located therebetween. Hence, the magnetic force between the two magnets can improve some disadvantages among the two mechanical structures and the mechanical bearings, such as friction and energy loss.
